A Series

A Series pumps are designed to operate at standard motor speeds, with provisions for flange or foot mounting. The C-faced flanged mounted pumps allow for a compact footprint while ensuring proper alignment with the motor.

Due to the helical design of the gears, the tooth profile is much stronger than conventional spur gears and runs quietly.

  • Quiet Running Helical Gears
  • Maintenance-Friendly Design
  • Long-Lasting Bearing Surfaces

Typical Applications

A Series

A Series pumps are adaptable to a wide range of applications for pumping clean fluids, such as pressure lubrication, hydraulic service, fuel supply, or general liquid transfer.

A Series Nomenclature

A Series Small

The figure number consists of a five, six, or seven digit number. The first and, in some instances, the second digits indicate the mounting arrangement and relief valve (RV). 

  • 1 = Foot mounted, No RV
  • 2 = Foot mounted with RV
  • 17 = Flange mounted, No RV
  • 18 = Flange mounted with RV
  • 25 = Baseplate mounted, No RV
  • 26 = Baseplate mounted with RV
  • 33 = Close Coupled, No RV
  • 34 = Close coupled with RV 

The next two digits indicate shaft sealing. 

  • AL = Lip Seal 
  • AM = Mechanical Seal 
  • AP = Packing 

The next two or three digits indicate the approximate theoretical displacement in US gallons per 100 revolutions [Liters/100 rev]. 

  • 005 = .005 [.019] 
  • 01 = .01 [.038] 
  • 02 = .02 [.076] 
  • 03 = .03 [.114] 
  • 06 = .06 [.227] 
  • 08 = .08 [.303] 

The next one or two letters indicate the direction of rotation and shaft position. The letter “L” indicates low drive. If the letter “L” is not used, the shaft position is high drive. Not all rotations are available for all sizes. CW = clockwise rotation; CCW = counterclockwise rotation. 

High Drive: 

  • No letter or W = CW (standard rotation for most sizes) 
  • X = CCW 
  • Y = CW 
  • Z = CCW 

Low Drive: 

  • LW = CW 
  • LX = CCW 
  • LY = CW 
  • LZ = CCW 

Occasionally, special pumps or configurations are required which are unique for a particular application. These modifications are clarified by a SPECification number. Identification of any items different than a standard pump can be made by consulting Roper Pump Company or an authorized distributor. 

The TYPE number is a number used by Roper Pump Company for in-house identification of construction. Always include the type number in any references to the pump. 

  • A = low pressure spring  
  • B = high pressure spring (standard) 

The SERIAL number is a unique number assigned to each pump built by Roper Pump Company. 

In any communication concerning this pump, always be sure to include the Figure, Spec, Serial, and Type numbers so proper identification of the pump can be assured.

  • AL = Lip Seal 
  • AM = Mechanical Seal 
  • AP = Packing 

The next two or three digits indicate the approximate theoretical displacement in US gallons per 100 revolutions [Liters/100 rev]. 

  • 12 = .12 [.454]
  • 16 = .16 [.606]
  • 21 = .21 [.795]
  • 27 = .27 [1.022]
  • 32 = .32 [1.211]
  • 40 = .40 [1.514]

The next one or two letters indicate the direction of rotation and shaft position. The letter “L” indicates low drive. If the letter “L” is not used, the shaft position is high drive. Not all rotations are available for all sizes. CW = clockwise rotation; CCW = counterclockwise rotation. 

High Drive:

Rebuild Kits

Major rebuild kits available for standard pumps. See distributor or manufacturer for more details.

A Series - Size & Specification Chart

Note: Maximum speed and flow can only be achievable under the correct inlet (suction) and liquid conditions. Liquid viscosity and discharge pressure, plus pumping conditions will determine actual flow (ie. – theoretical minus slip).
